Firefox Community Forum

I was excited to see that Firefox had support for Canadian English, however the dictionary seems to be missing numerous words and I get spelling errors for words like "lasagna."

Is this a bug or is the dictionary just barely populated with words and missing a tremendous amount?

I often receive a 403 error when using Firefox Every time, before this happens, I get the unsafe website warning and then the 403 error when I continue anyway

I am using the latest version at the time of writing These errors only occur on my desktop PC I have tried to replicate this issue on both my phone (Android) and another laptop(Windows 11) but all the websites work normally on there.

I have tried the following, none of which have any effect:

• Clearing cookies
• using Troubleshoot mode
• Restarting
• Changing Useragent
• Using "Forget about this site"

The following do fix the issue

• Using a VPN
• Using Google Chrome
• Running Firefox in another profile

Going through the privacy and security tab and reseting all the settings sometimes works but only temporarily

The following are a few websites where the issue occurs

1. https://kdice.com/
2. https://latinitium.com/
3. https://theysaidso.com/
4. https://opensource.org/
5. httpe://obsidian.rocks/

Well looks like they did it to us again. My tabs are back on top again and need to put them below where I am a lot of other users like our tabs!

Below is my current coding if anyone knows how to adjust it to force the tabs to the bottom again would be much appreciated!!

Current version I am running of FF is 133.0

When the latest version is released, if I continue browsing without pressing the update button, the process suddenly becomes slow or freezes until I restart the device. Why is this? There are no problems until the update arrives, but as soon as the update arrives, the device becomes unstable, and after the update, it works as if nothing happened.

　I am using Google Translate, so the nuances may be different.

I have the setting browser.search.openinnewtab and also browser.urlbar.openintab both set to true, but when I type a search into either the address bar or the search bar next to it, instead of opening a new tab, it puts that search into an already-open blank tab, if one is already open.

I often use blank tabs to separate my currently open tabs into groups by topic and whatnot, so it's incredibly annoying when the search bar takes over one of my adhoc 'separators' instead of opening a new tab like I want it to.

Is there a setting to force the search bar to always open a brand new tab, even if 'new tabs' are already open??

My search bar is taking up the entire screen when I try to interact with it. When I go to search stuff, then it returns to the normal style. Then, when I try to interact with the page I'm on, it absorbs the screen.

I never feel like webpages scale properly when I visit them. There is always content left off screen or I have to zoom out so much that the text is too small to read. Is there a setting I can change to affect this?

This webpage is particularly egregious: https://www.desktopmetal.com/products/shop

My Firefox Nightly version is: 135.0a1 (2024-11-26) (aarch64). My computer is a: MacBook Air (15-inch, M2, 2023) running macOS Sequoia (Version 15.1). I have been having these issues for a long time regardless of computer.

I have attached a picture of the labs settings I have enabled but I cannot see why any of them would affect this.

The latest update to Firefox includes a new Review Checker. It is activated by pressing the price tag in the address bar when on a specific product page in Amazon, etc. This price tag does not appear on my laptop when I am on a product page. Is there an activation method I am not using? How do I get the price tag to appear?

I've asked about this before but got no help Firefox is my browser of choice. Occasionally, I find in necessary to use Chrome.

The vast majority of time, when are both are active at the same time, one or both crash, like today. Firefox closed abruptly, then the crash report appeared. I have the crash report. Chrome froze up, and had to be shut down in Task Manager.

It only occurs in this scenario. Rarely does Firefox crash otherwise.

Can someone please advise where to go to get help?

Hello, I have uninstalled and reinstalled firefox twice using two different ways found on the community/mozilla website through chrome and I am still having trouble. It started a couple weeks ago when I received a notice at the top right hand of my firefox page for an update. I tried and it shows as Unable to connect. I tried various ways to connect with mozilla with no luck. I uninstalled, restarted my computer and reinstalled twice and still having the same issue. I lost all my plug ins and add ons after the reinstall and now I can't not even get them and can no longer sign into my firefox account through firefox. Anything that has to do with mozilla I can not reach unless I use chrome which I don't like doing. I have searched the community and nothing seems to help and I even submitted a help question in help community but no responders. Anything which I found addressing Unable to Connect was years old anyway. I can only assume it had to do with the update pop up which I never got to do and assumed a refresh or a reinstall would take care of it but it hasn't. What can I do? Thank You, Charyl

Got a new W11 computer and I know I've stopped it before.

I found https://support.mozilla.org/en-US/questions/1284577 on a search, but that didn't work and the answer is archived so I can't comment on it.

Where are the valid instructions?

Also, should I undo that? What other things might that now be doing?

I believe there is a memory leak (or memory growth) bug in Firefox 133.0 on Windows 10. It's site-specific. I am trying to login to my account at https://www.ssa.gov/, and it never actually gets to the login prompt. Using the Windows task manager, I can see the RAM usage keeps increasing, until it nears the 12 GB installed RAM capacity, at which time I kill the firefox process. I'd say this is a bug in ssa.gov, except the problem does not occur with the google chrome browser.

To provide further detail, I go to site https://www.ssa.gov/, and click on the "sign in" button. That takes me to the page where you choose the login method (id.me or login.gov) and I choose "id.me". It takes me to the "you are leaving Social Security's website " message, which is still on the ssa.gov website. At that point, firefox memory usage starts to increase, as shown in task manager. The browser never advances to the next page, but main memory usage keeps going up. This goes on for about 30 seconds before I have to kill the firefox process.

What can I do to have Firefox be compatible with my emails. When I open an email for the local newspaper, the news paper is distorted and enlarged 200% and asks me to sign in. Everything was fine until the most recent Firefox update.

I want to remove the recent update which results in Firefox and some of my email links to be incompatible. The newspaper link works on Safari but I do most of my activity on Firefox.

Also, the email link works fine on Google Chrome. But I hate Google Chrome and don't want to use it. I would prefer that the Firefox browser be compatible with sites such as my local newspaper.

Why do I keep getting pop-ups that 500% zoom in on the page with a message asking for me to clear cache? I have cleared my cache multiple times and restarted my computer many times as well, but it is still been a recurring problem for the past few days. It has been happening on every web page I visit, and even when there is no data to be cleared. Any information on how to fix this problem would be greatly appreciated, thank you.

I've encountered a bug in Mozilla Firefox where the browser becomes unresponsive when using Solid State Drives (SSDs), specifically PCI-E 3.0 SSDs with a 960GB M.2-110mm drive https://serverorbit.com/solid-state-drives-ssd/pci-e3-0-ssd/960gb-m-2-110mm. The issue seems to occur when multiple tabs are open, and the browser struggles to keep up with the data processing. Has anyone else experienced this issue, and are there any known fixes or workarounds?

FedEx updated their website and you can't see the legacy site anymore. I am not able to view/print FedEx invoices on Mozilla - but it works on Microsoft Edge. Why can't I view/print from Mozilla?

Thanks for your help!

As of v133 the system color is now longer shown at the top of the page. Everything at the top is now gray which I find to be very irritating. Please return the system color functionality.
